How do air masses interact to form a tornado? o a. cold, dense air flows toward the warmer, less dense air, so the cold front ends up moving faster than the warm front. o b. a cyclone rotates faster and faster as pressure differences between areas of low and high pressure increase. o c. a cyclone becomes slower and slower as pressure differences between areas of low and high pressure decrease. o d. two air masses meet, but neither moves into the other one and spiral wind results.
